Cnidaria are diploblastic, only consisting of 2 body layers, no cephalisation and limited nervous system and musculature. Annelida however, is triploblastic (with 3 body layers). Members are also coelomate with a body cavity for organs. Bilateral symmetry allows for mouth AND anus to differentiate. With a body cavity there is need for greater circulation, nervous control and excretory apparatus. Musculature is quite good, for movement. There are many such characters that make Annelida more advanced. Annelida are also (in the case of their class Oligochaeta) more terrestrial, whereas Cnidaria are entirely aquatic.

Which of the animal phyla was the first to evolve three germ layers?
The first animal phylum to evolve three germ layers was the Cnidaria. These germ layers are the ectoderm, endoderm, and mesoderm, found in more complex animals for the development of different structures and organs.
What is the kingdom phylum class order family genus and species of a jelly fish?

Is genius larger than a phylum?
No, a phylum is a taxonomic rank higher than genius. A phylum contains one or more genuses.
What characteristics of the Phylum Nematoda make them more advanced than previous animal phyla?
Some characteristics that make Nematoda more advanced include their presence of a pseudocoelom, a complete digestive system with a separate mouth and anus, and a more developed reproductive system with separate sexes. They also display a greater diversity in habitat and feeding strategies compared to previous animal phyla.
Who has more members a phylum family or a genus family?
A phylum contains more members than a family. A phylum is a higher taxonomic rank that includes multiple families. On the other hand, a family is a lower taxonomic rank that includes multiple genera.
Is jellyfish really a fish?
No. It is a very ancient hollow animal. It used to be in a group of animals called 'Coelenterates', meaning, "Hollow", but have more recently been reclassified.Jellyfish are not fish and are actually members of the phylum Cnidaria, not Chordata.
Is an earthworm a flatworm?
No, flatworms are from the phylum Platyhelminthes, while worms are from the phylum Annelidia. Worms are more developed and have a coelum, while flatworms have no coelum at all.
What is the Latin name for jellyfish?
Jellyfish are members of the phylum Cnidaria. There are more than 100 kinds, each with its own Latin name. So there is no single Latin name for jellyfish.

What organisms with tentacles is least related to others?
Sea anemones are the least related to other organisms with tentacles. While they belong to the same phylum Cnidaria as jellyfish and corals, they are considered a more basal or primitive group within this phylum and show distinct differences in their biology and behavior compared to other organisms with tentacles.
What is the kingdom phylum order class family genus species of the box jellyfish?
Kingdom: Animalia Phylum: Cnidaria Class: Cubozoa, Hydrozoa, Polypodiozoa, Scyphozoa, Staurozoa There are at least 12 orders. There are at least 63 families. There are over 200 species of Scyphozoa, about 50 species of Staurozoa, about 20 species of Cubozoa, and in Hydrozoa there are about 1000-1500 species that produce medusae (and many more hydrozoa species that do not).
What is phylum and what is sub phylum?
A phylum is a group of animals that are directly drawn from a kingdom. A sub-phylum is a phylum that is slightly more accurate for a group of animals but is not a class.
What do flatworms have that sponges and cnidarians dont?
Flatowrms have muscle cells, they are a triploblastic phylum. They have endo, meso and ectoderm layersSponges are Parazoa and lack any true tissue at allCnidaria are diploblastic, having only endoderm and ectoderm
What is the difference between Brain Coral and Fire Coral?
From a visual standpoint a brain coral is rounded and looks much like a brain, hence the name. Fire coral can be branching, encrusting or plate forming and are more closely related to jelly fish and anemones than true corals. Fire corals are Phylum: Cnidaria Class: Hydrozoa Order: Anthomedusae Family: Milleporidae Genus: Millepora With 13 + species Brain Corals are Phylum: Cnidaria Class: Anthozoa Order: Scleractinia Sub Order: Faviina Family: Favidae Genra: approx 19 genus and their associated species
Is phylum more inclusive than kingdom?
No. The heirarchy goes...kingdom, phylum, genus, species, so kingdom is the broadest of the terms, and phylum is more specific.
Types of coelenterata?
There are two other groups Cnidaria and Ctenophora:A.) Cnidaria also known as coelenterates, diverse group of aquatic, invertebrate animals armed with microscopic stinging structures. Cnidarians make up the phylum Cnidaria, which encompasses more than 9,000 species, including corals, hydras, jellyfish, Portuguese man-of-war, and sea anemones. Cnidarians live in all oceans, and a few species inhabit fresh water.B.) Ctenophora are jellyfish-like marine animals distinguished by eight rows of cilia that propel the body in swimming. They feed on other invertebrates using two retractable sticky tentacles to capture prey. All ctenophores are hermaphroditic and reproduce sexually. Many are luminescent.
